Composite Door Prices: Supply & Fit Costs Explained

How much does a composite door cost?

A composite door typically costs around £1,000–£3,000+ in the UK when supplied and professionally fitted, though prices vary with the door's construction, size, design, glazing, hardware, and installation requirements.

For supply-only, composite doors can start at around £450–£800, while more highly specified doors can cost £1,000–£1,200 or more.

The final cost depends on the specification you choose and the work required to install the door, so it's best to compare quotes based on the complete doorset and installation, rather than the door price alone. To put those differences into perspective, composite doors can broadly be grouped into entry-level, mid-range and premium options.

Entry-level composite doors

At the more affordable end, you'll find composite doors with relatively straightforward construction and standard specifications. These may have a basic foam-filled core, a simple finish, limited colour choices and little or no glazing.

Buying supply only can bring the initial price down further, particularly if you already have an installer or are arranging installation separately.

Mid-range composite doors

Moving up the price range, composite doors tend to offer more choice and a higher level of specification. You may have a wider selection of colours and finishes, more glazing options, upgraded hardware and different door styles or configurations.

At this level, you're paying not only for the door itself but for greater flexibility in how you customise it to suit your home.

High-end or premium composite doors

At the premium end, the price can reflect a more advanced engineered door system rather than simply additional cosmetic options.

Premium composite doors such as Rockdoor are designed around a more sophisticated construction, with features and manufacturing processes intended to deliver a higher level of security, thermal performance, durability and finish.

For example, Rockdoor uses premium foiled skins, S-Glaze technology and a reinforced inner core, rather than simply adding more options to a standard composite door. This difference in construction and manufacturing is one reason why a premium composite door can cost more than an entry-level alternative.

It's important to check whether a price you're seeing is for the door alone or for the complete installation.

What’s included in a fitted composite door price?

A fitted price can also include the removal and disposal of your old door, surveying, measuring and making good around the entrance.

A supply-only price may cover the door and its basic components, but you could still need to pay separately for:

• Removal and disposal of your existing door
• Installation
• Making adjustments around the opening
• Any structural or remedial work

A supplied-and-fitted quote gives you a much clearer picture of the total cost of replacing your door. Professional fitting alone can add a few hundred pounds to a straightforward replacement, and more complex installations cost more.

Always check what is included in the final quote before comparing one price with another.

A £1,200 quote that excludes installation isn't necessarily cheaper than a £1,600 quote that includes the complete installation.

What factors influence the price of a composite door?

Several factors can affect a composite door quote.

The main ones are:

1. Door materials and construction
2. Size and configuration
3. Door style
4. Glazing
5. Door Furniture
6. Security features
7. Frame and threshold
8. Installation requirements
9. Your choice of door manufacturer and installer

Let's look at each one.

1. Door materials and construction

Not all composite doors are built in exactly the same way.

The materials, inner core, thickness of sash, outer skin and overall construction can vary between manufacturers. This is one reason why comparing doors purely on price can be misleading.

A lower-priced door may have a different construction or specification than a premium composite door, even if they look similar from the outside. The price of a composite door reflects more than its appearance.

For a deeper look at what to consider before choosing a door, see our composite doors buying guide.

2. Door size and configuration

The size and layout of your entrance can have a noticeable effect on the final price.

A standard single door will generally cost less than a larger or more complex entrance.

For example, you might be considering:

• A standard front door
• A wider entrance with a side panel
• Two side panels
• A top light
• French or double doors
• A stable door
• A bespoke configuration

Additional glazing, frames, and structural components all contribute to the overall specification, which can affect the final quote.

This is particularly important if you're replacing an existing entrance with composite doors with side panels, where the additional glass and frame sections can increase the cost.

If you're considering composite doors with side panels, read our complete guide to explore your options.

3. Door style

The style you choose can also affect the price. Some designs are relatively simple, while others involve more detailed panel designs, glazing arrangements or glass designs.

However, don't assume that a more expensive-looking style is automatically better.

The best approach is to choose a style that suits your home and then compare the complete specification and price.

If you're still deciding which design is right for your property, our front door styles guide can help. Alternatively, use our 3D Door Designer to create your ideal door and visualise it on real homes.

4. Glazing

Glazing can make a significant difference to both the appearance and price of a composite door.

A simple glazed panel may have a different cost from decorative, obscure or exclusive glass designs such as 3D Glass from Rockdoor.

The glass itself isn't the only thing that can affect the price of a composite door. How the glazing is fitted into the door can also make a difference.

Some doors use a cassette system to hold the glass in place. This can be a more cost-effective approach, while Rockdoor uses S-Glaze, which securely locks the glazing unit within the door frame rather than relying on a conventional external cassette. This gives the glazing a clean, premium appearance while forming an integral part of the door's construction.

When comparing quotes, it is therefore worth looking beyond the type of glass and checking how the glazing is actually fitted.

5. Door furniture and accessories

Handles, knockers, letterplates and other door furniture may seem like small details, but your choices can affect the final price.

Premium or upgraded hardware can increase the overall cost, so check whether your chosen options are included in the initial quote.

If you're unsure which hardware to choose, our composite door hardware and accessories guide covers the options in more detail.

6. Security features

Security is another area where specifications can differ between composite doors.

A basic quote and a premium quote may include different locking systems, cylinders or additional security features.

When comparing prices, look beyond the number of locks and consider the complete security specification.

For example, Rockdoor includes a 3-star cylinder with Active Snap Protection as standard, while additional security features such as Steel Mesh can also be selected for extra security.

Explore Rockdoor security features to see how they're designed to help protect your home.

This is a good example of why the cheapest quote isn't always the most useful comparison.

7. Frames and threshold

It's easy to focus on the door itself when comparing prices, but the surrounding doorset can also affect the overall cost.

If you're replacing the complete entrance, make sure you understand whether a new frame is included.

A replacement will typically involve the door leaf, frame and threshold, and the dimensions and condition of your existing opening can determine how straightforward the installation will be.

If you're choosing a wider entrance with one or more sidelights, you'll need additional framework and glazing alongside the main door. This increases the amount of material and installation work required, so a door with sidelights will generally cost more than a standard single-door configuration.

8. Installation requirements

Installation is an important part of the overall cost of a composite door if you are considering a fully fitted door. A straightforward replacement may be relatively simple, while a more complicated entrance could require additional work.

Depending on your existing entrance, the work could include removing the old door and frame, making adjustments to the opening, making good around the new frame or carrying out minor brickwork repairs. Larger configurations, such as doors with side panels, may require additional installation work too. The disposal of your old door can also affect the overall installation cost.

This is why the price of a fitted composite door can be more useful than looking at supply-only prices. You're seeing the cost of the complete job rather than just the door.

9. Door manufacturer and installer

The manufacturer and installer you choose can also influence the final price.

Different manufacturers use different construction methods, specifications, materials and levels of customisation. See how Rockdoor compares with other composite door manufacturers and explore the key differences in their approaches.

Labour costs can vary between installers depending on their experience, expertise and the level of service they provide. While a lower quote may look appealing, the cheapest option isn't always the best value.

Rockdoor uses a made-to-measure approach, with each door priced according to the dimensions, design and features selected. We work through a network of 200+ Trusted Installers who can survey the property and provide a tailored quote.

Composite door prices compared with other door materials

Composite isn't the only option. uPVC, wood and aluminium doors each offer a different balance of cost, appearance, performance and maintenance.

As a general indication, uPVC and wooden doors tend to be the most budget-friendly options, while composite doors typically sit above them. Aluminium doors can overlap with or exceed composite prices depending on the specification, size and installation requirements.

If you're weighing up your options, our composite doors buying guide includes a broader comparison of composite, uPVC, timber and aluminium doors.

How to get an accurate composite door quote?

Online price ranges are useful for setting a budget, but they can't tell you exactly what your new door will cost.

For an accurate figure, you'll normally need to choose your preferred specification and have your entrance assessed by a local installer.

A good quote should take into account:

• Door size
• Door type and style
• Door Colour
• Glazing
• Door Furniture
• Security specification
• Frame and threshold
• Installation
• Removal and disposal of your existing door
• Any additional work required

For Rockdoor, you can start by choosing your preferred design and customising it with colours, glazing and hardware using the 3D Door Designer. Your chosen details can then be discussed with your local Rockdoor Trusted Installer to create a tailored quote.

How to compare composite door quotes?

Getting several quotes can help you understand what you're paying for, but make sure you're comparing like for like.

One quote might include a premium glazing option, upgraded hardware and full installation, while another might be based on a simpler specification.

It's also worth checking whether there are any potential additional charges. A good quote should make it clear what you're paying for.

Don't compare the price alone

A composite door is something you will use every day for many years, so the cheapest quote isn't automatically the best value.

Consider the whole package:

Door + specification + installation + guarantee

That's a much better way to judge value than simply comparing the headline figure.

How much should you budget for a composite door?

If you're at the early research stage, a sensible starting point is to allow roughly £1,000–£3,000 for a supplied and fitted composite door, while understanding that your final price may sit outside this range.

A straightforward single door with a simple specification is likely to sit towards the lower end.

A larger, highly customised or premium door with additional glazing, upgraded hardware or more involved installation can move towards the upper end or beyond it.

The best way to establish your actual budget is to decide which features matter most to you, then get a tailored quote from your local installer based on your home and chosen specification.

The cost of a composite door ultimately comes down to what you choose and what your home requires.

Rather than focusing on a single headline price, consider the construction, security, thermal performance, design, glazing and installation that you want from your new door.

With Rockdoor, you can customise any front door style, colour, glazing and hardware using our 3D Door Designer.
